My dropper has always been 1/4" too high but the pivot bolt won't let me insert the post any deeper. I finally had enough and took it apart and a large ty wrap is the same width and thickness as the guide bushes and they bump a delrin sleeve at the top of the the travel. I compressed the post a little, cut 1/4" lengths of the ty wraps and maneuvered them into the guide channels and put the whole thing back together. My 125mm dropper is now 120mm(okay, 118.65 but you get the point) and it's not too high anymore!
